Definitions

  • the present invention relates to an accident-preventing safety device for automatic moving closure barriers, such as doors, gates, overhead doors, and the like.
  • a conventional type of safety device uses photocells and/or electronic sensors that are arranged appropriately and are connected to the control unit of the automatic barrier.
  • a drawback of these conventional safety devices is their excessive cost; in order to achieve a high degree of safety it is in fact necessary to use several sensors and the corresponding drive systems, whose high cost is well-known.
  • Another drawback of conventional devices is constituted by the frequent false interventions of the sensors; for example, to trigger the intervention of the safety device it is sufficient for an insect, or an object floating in the air, to cross the path of the photocell.
  • a safety device which includes a profiled part rotatably hinged to the closing edge of the automatic barrier, with a pressure switch that is interposed and connected by virtue of a feedback line to the control unit of the automatic barrier.
  • the pressure switch is operated in the presence of forces that act on the profiled part, are directed against the closing edge, and are generated, for example, by obstacles that are present along the closing path of the automatic barrier.
  • the activation of the pressure switch stops the motor of the automatic barrier and optionally reverses the direction of its motion.
  • This conventional device despite being relatively simple and cheap, is difficult to adjust and has the drawback that does not ensure quick and precise intervention in any operating condition.
  • the pressure switch can frequently malfunction.
  • the aim of the present invention is to eliminate the above drawbacks by providing an accident-preventing safety device for automatic barriers that is quick-acting, reliable, and strong as well as suitable for operation in any environmental condition.
  • an object of the invention is to provide a safety device that is simple and cheap and can be applied to any kind of gate, door, and automatic barrier in general.
  • a device as described in the preamble of claim 1 including a first part that is pivoted to a second part that can be anchored to a closing edge of an automatic barrier and elastic contrast means interposed between the first and second parts to keep them usually mutually spaced, characterized in that it comprises electric switching means adapted to stop and/or reverse the motion of the automatic barrier in the presence of external forces that act on the first part and contrast the elastic means.
  • the switching means are constituted by at least one electrical microswitch, which is anchored to one of the elongated parts and interacts, for actuation, with a protrusion which is formed correspondingly on the other elongated part.
  • This configuration in addition to being very simple and functional, drastically reduces the production, maintenance, and assembly costs of the safety device.
  • the accident-preventing safety device is applied to an automatic gate A of the sliding type at the vertical closing edge C.
  • the safety device 1 includes a first elongated part 2, which is constituted for example by a profiled part made of synthetic or metallic material and hinged along a longitudinal axis 3 to a second elongated part 4, which is also constituted by a profiled part and can be anchored to the closing edge C of the automatic gate A.
  • Elastic contrast means are interposed between the two profiled parts 2 and 4 and are adapted to keep them mutually spaced toward the end that lies opposite to the hinging end.
  • the elastic means can be constituted for example by at least one spring 5 of the flat, wire, or spiral type, the opposite ends 6 and 7 thereof being inserted in adapted seats 8 and 9 formed in corresponding positions on the inside walls of the two profiled parts 2 and 4.
  • electrical switching means are provided which are suitable to stop and/or reverse the motion of the automatic gate A in the presence of external forces which act on the first profiled part 2 and oppose the contrast force of the spring 5.
  • These switching means are constituted by an electrical microswitch 10, which is anchored to the inside wall of the part 4 and provided with a button 11, which faces a protrusion 12 formed on the other part 2.
  • the microswitch 10 is connected, either directly or indirectly by virtue of a relay, to the control unit of the driving motor (not shown) of the automatic gate A.
  • the microswitch 10 operates in low-voltage safety conditions and is of the sealed type suitable for outdoor environments.
  • the microswitch 10 is preferably of the monostable and normally-closed type, so that upon actuation it immediately interrupts the flow of current flowing through it, immediately halting the motor of the automatic gate A and optionally reversing the motion of the motor.
  • the safety device according to the invention can also be easily fitted to overhead doors, main doors, sliding gates or side-hung gates, even if these have already been installed.
  • the accident-preventing safety device according to the invention is subject to numerous modifications and variations, all of which are within the scope of the inventive concept expressed by the accompanying claims. All the details may furthermore be replaced with other technical equivalents that are understood to be equally protected.
  • the materials, the shapes, and the dimensions may be any according to the requirements.
